Patent GB-1576889-A (GB)
Title: Optical fibres
IPC: G02B6/38
Filed: 1977-04-28
Abstract: Sleeve-shaped end pieces for optical fibres whose naked end is inserted into the central bore of a watchmaker's stone (4) fastened to a sleeve end and centred and fixed there, are already known. The present invention describes a technique by means of which it is possible to use the known technical operation to mount in the end piece even fibres provided with a plastic coating (21). In this case, two particular basic problems are solved, specifically the defective centring of the optical fibre core (1) in the plastic coating (21), and, in addition, the problem of the loss of light due to the exit of the light "sideways" from the naked core, i.e. along its cylindrical longitudinal surface, into the adhesive (5). The first problem is solved by peeling off the plastic coating (21) at the fibre end and re-embedding the exposed fibre core (1) in an appropriate adhesive (5). The second problem, the escape of the light, is addressed by applying a highly reflective layer (6) around the naked fibre core. <IMAGE>

Abstract: 618,784. Gas burners. LOVELL MANUFACTURING CO. June 13, 1946, No. 17800. Convention date, June 15, 1945. [Classes 75 (i) and 75 (iii)] In a gas burner substantially all the combustion air is supplied to a combustion air chamber in the form of a vortex having its greatest velocity at the periphery and decreasing in tangential velocity towards the centre, the vortex spirals along the combustion chamber in axial progression and a gas injection nozzle projects into the core of the vortex in the direction of progression of the spiral. A scroll shaped combustion air chamber 2 to which air is admitted at high speed tangentially through a radially narrow inlet nozzle 4 connected to a blower communicates on one side with a conical fuel injection chamber 3 into which a gas nozzle 8 projects and on the other side the combustion air chamber communicates through a restricted throat 7 with a combustion tube 1. The burner is ignited by an electric heater coil 11 mounted in an annular chamber 13 at the outer end of the fuel chamber 3, an annular plate 15 shielding the coil 11 from the combustion heat. Combustion failure protection and a time delay between the starting of the combustion air and the injection of gas are provided by a the;mostatic element 16 mounted in the air chamber 2 and an electric heater coil 18 (Fig. 4) adjacent the thermal element. The gas nozzle 8, which may have a Venturi throat provided with inlets in its walls through which air can be drawn, may be supplied from a tangentially fed gas chamber or from a gas line 9 with a metering orifice 10 and may discharge through an annular baffle plate 8b. In the electrical control circuit (Fig. 4) a switch 25 connects the supply to an air blower motor 6 and through a contact 17, made by the thermal element 16 when cold, to the ignition coil 11 and the coil 18 heating the thermal element 16 and the combustion air. A relay 21 is simultaneously energised to close contacts 22 connecting a solenoid valve 20 in the gas line 9 to a contact 19. When heated the thermal element opens the contact 17 and closes the contact 19 and as the contacts 22 do not open immediately, the solenoid valve 20 is energised and contacts 23 of a holding circuit are closed. The motor 6 is protected by a thermal overload device 28. Modifications of this electrical control circuit are described.

IPC: A61G10/02
Filed: 1963-05-07
Abstract: 1,010,727. Fluid-pressure servomotor systems. NORMALAIR Ltd. July 30, 1964 [May 7, 1963], No. 17900/63. Heading G3P. [Also in Divisions B7 and F4] A pressure chamber 1 is provided with an airlock 2 having inlet 8 and outlet 9 for ventilating and pressurising airflow through the airlock, controller means 16A being provided for controlling automatically or manually the rate of airlock pressure change and for maintaining a constant pressure by controlling valve 25 associated with outlet 9. As shown in Fig. 2, controller 16A comprises a chamber 16 which is connected to the atmosphere via valve 28 and pipe 18. Valve 28 is controlled by an evacuated capsule 30. A selected pressure inside chamber 16 is communicated through pipe 19 to relay 33 the lower chamber 37 of which communicates with the airlock through filter assembly 39. The movement of diaphragm 35 and hence the pressure in the lower chamber is responsive to the pressure in controller 16A. A further housing 40 is formed adjacent valve 25 and communicates with chamber 37. The controller 16A thus controls the position of valve 25 and the pressure in the airlock. Capsule 30 may be raised or lowered by means of cam 45 which can be slowly rotated by means of a pair of solenoid actuators 47. The cam varies the position of the valve member 26 and hence the pressure controlled by the valve 25. The pressure chamber 1 has a similar controller 10 and a differential pressure switch 49 is arranged to ensure that the airlock pressure can never exceed the pressure in the main chamber. Cam 45 of controller 16A and the equivalent cam of controller 10 each have a rotary potentiometer attached hereto for sensing the position of each cam and comparing cam positions in order to prevent cam 45 from being driven to a position corresponding to a greater pressure then the pressure in the chamber 1.
